Fig. 6.

Accuracy. Each of the six panels shows the accuracy for five behaviors (stand still, walk, skip, jump, and a second stand still) in four participants for one eye tracker. This error is defined as the unsigned median distance between the target and the gaze directions in degrees. Error bars denote standard error of the median. In most cases, these errors are so small that the error bars are occluded by the plot symbol. Note that the data point for the second stand still episode for the blue participant for the Pupil Invisible is missing (we found out about the omission when the participant had already left Lund)
